6 Claims. 1

The invention relates to roofing and/or siding. Those types of roofing or siding in which metallic roofing or siding sheets have their side edges upturned or flanged, either to form a standing seam or a batten seam have often not proven satisfactory because their construction has been such that sufficient free lengthwise movement due to contraction or expansion of the sheets has not been permitted. Also, in case of standing seam roofs, destructive total area horizontal movement has often been unintentionally allowed. Either of these faults lead to quick failure of the roof. Furthermore, the joints of the standing seam or batten seam roofing or siding have been formed or finished on the job, making the labor cost of such roofing or siding a large part of the totalcost.

In my prior United States Letters Patent No. 2,356,833, dated August 29, 1944, these difiiculties have been overcome by the joint structure therein shown and described which includes a plurality of spaced clips by which the roofing sheets or plates are held down against the roof. The object of the present invention is to simplify and improve the onstruction of the above mentioned patent by eliminating the clips and using cover members to function both ascovers and hold down means for the roofing or siding plates and further increasing the hold down area. With the structure herein described, the roofing or siding plates are not only held in their applied positions, but permitted free lengthwise movement due to temperature change any horizontal movement in any sheet is prevented from affecting or exerting pressure on the next adjoining sheet.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a perspective View of a roofing structure embodying the invention;

Fig. 2 is an enlarged detailed vertical sectional view through the seam or joint;

Fig. 3 is a detailed plan view of the joint, parts being broken away and parts shown in section;

Fig. 4 is a view similar to Fig. 2 showing certain modifications; V

Fig. 5 is a view similar to Fig. 2 showing another modification;

Fig. 6 is a perspective view of one of the roofing sheets;

Fig. 7 is a view similar to Fig.6 showing certain modifications;

- upturned edges are associated with a batten strip;

Figs. 10 and 11 are views similar to Fig. 9 showing modifications thereof.

Referring to Figs. 1 to 8 of the drawings, the roofing or sidin material is in the form of plain sheet metal l2 with upturned or flanged sides I3 having inwardly inclined upper edge portions I4, as shown in Fig. 6, or of sheet metal having transversely extending corrugations in its body IS with upturned or flanged sides l6 having inwardly inclined upper edge portions ll, as shown in Fig. '7, the corrugations serving to strengthen the sheet when made of thin gauge metal. The sheets or plates of definite predetermined lengths are associated together lengthwise by overlapping the lower end of an upper plate with the upper end of a lower plate which upper end is secured to the frame of the roof by nails I8 or other suitable fastening means, as shown in Fig. 1. Thus lengthwise expansion of each plate is permitted. Lengthwise extending lengths of assembled plates are arranged next to similar sets of assempled plates at each side and are joined together by cover members 20 secured to the roof, so that they are free to move lengthwise relative to each other and relative to the roofing plates.

The cover members 20 are of definite predetermined length preferably considerably less than that of the roofing or siding plates as shown by comparison in Figs. 6 and 8 and are made of sheet metal formed to provide a hood or channel structure whose top or web 2| abuts the out turned top of the edges I4 or I! of the roofing plates and whose sides or flanges 22 abut or yieldingly engage the sides I3 or [6 of the roofing plates. These cover members are associated together lengthwise by overlapping the lower end of an upper cover member with the upper end of a lower cover member which upper end is secured to the frame of the roof or siding by long nails 23 which pass through the top or web of this end of the cover member and thereby cause this cover member to exert a hold down action on the adjoining plates and also permit the relative lengthwise movement of the cover plates to each other and to the roofing or siding plates, and since these cover members yieldingly engage the sides of the roofing or siding plates, lateral expansion of the plates is also permitted. In order that these cover members when assembled together and secured to the roof or siding as above noted may act as a. continuous lengthwise extending.

hood or channel the sides 22 have a slidably interlocking connection with each other. This interlocking connection may be in the form of a series of interlocking lengthwise extending curved corrugtions 24, as shown in Figs. 1 to 3, or a single curved flange connection 25, as shown in Fig. 4, or a sharply bent V-type corrugation 26, as shown in Fig. 5. With such interlocking connections the interlocking of the lower unfastened end of an upper cover member with the upper fastened down end of a lower cover member acts to bring the remainder of each of the cover members into hold down relation with the top edges of the sides of the roofing or siding plates. As shown in the drawings, these cover members are preferably tapered lengthwise, being wider at the end (here shown as the lower end) which interlocks with the upper end of the lower cover member than at their upper end, this taper or difierencerin section between the ends of said cover members being preferably equal to twice the thickness of the metal sheetfrom which said cover members are formed.

- The edge portions l4 or I I of the roofing or siding plates are bent inwardly so as to provide a space to permit quick and ready insertion of the nails 23, but the sides of the plate may be formed continuous or all in one plane, if desired, it being noted that these sides form an obtuse angle relative to the base portion of each plate.

} The cover members may be pre-formed, and their flanged sides will permit their interlocking engagement with each other by snapping or pushing down the upper cover member over the lower fastened down cover member. It will also be noted that the flanged or corrugated construction of the sides of these members provides one or more air pockets, which act to stop capillary action of moisture or water and thus prevent this moisture or water creeping up over the tops of the sides of the roofing plates.

The cover members above described may be formed at the factory or in some instances cover strips initially formed to a readily stackable form may be finished formed at the site of the work.

I In those cases where it is desired to more widely separate adjoining sections of the roofing or siding from each other as by a batten strip 21, the joints shown in Figs. 9 to 11 may be used.

f In Fig.9 the tops 28 of the cover members 29 are made wider so as to extend .over the tops of the strips 21 as well as thesides of the roofin or sidin plates and may be secured to the strips at one end by nails 30 which may also fasten said strip to the roof frame. Except for the top edge, the sides of the roofing plates are free of the strips 21. As in the first form, the sides 31 and the cover members 29 are corrugated and similarly associated with each other and with the roofing or siding plates.

The cover members 32 are similar to the members 29 except that; only a single interlocking corrugation 33 is provided at each side at the lower edge, and these members are anchored by nails 34 to the strips 21 and to each other and to the plates in a manner similar to the first described form.

The cover members 35 are similar to the cover members 32 except that the grooved interlocking connection 36 between adjoining cover members is at the upper portions of the sides of said members instead of the bottom portion.

The cover members 29, 32, and 35 may in each instance be brought into engagement with their adjoining member by being snapped or pushed down over said member, and in each instance the cover members and roofing or siding sheets are free to move lengthwise relative to their adjoining members and to each other.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
